Answer:
8π(2.5)^2
Step-by-step explanation:
volume = π * r^2 * h
v = π * (2.5)^2 * 8
FOIL and PEMDAS are both ways to solve mathematical equations.
<u>FOIL</u><u />
First
Outside
Inside
Last
<u>PEMDAS
</u>Parenthesis
Exponents
Multiplication &
Division
Addition &
S<u />ubtraction
FOIL is usually used to solve equations in two sets of parenthesis, for example:
(23+x)(5-4x)
PEMDAS is used to solve multiple-operation equations, such as:
5 x 4 + 6 - 2 x 7
Whew, hope this helped :D
Given:
<span>mantle layer of earth begins about 70 kilometers underneath the surface
</span><span>outer core begins about 2970 kilometers underneath the surface
Since we need to find the position of each layer </span><span>relative to the surface, the surface will serve as the point of origin or 0. Below the surface infers a negative value. So, Mantle layer is -70 km from the surface while outer core is -2970 km under the surface.
Comparing -70 and -2970, -70 has a greater value than -2970. The nearer the number is to the origin or 0, the higher its value.
Comparing the absolute greater value of -70 and -2970, -2970 has a greater absolute value. This is because absolute value is the positive value of the number. Absolute value of -70 is 70 while absolute value of -2970 is 2970. Thus, -2970 has a greater absolute value. </span>
Answer:
the 4th option is correct
Step-by-step explanation:
Original expression
Split up the exponent
![x(\sqrt[9]{y^{2} } )](https://tex.z-dn.net/?f=x%28%5Csqrt%5B9%5D%7By%5E%7B2%7D%20%7D%20%29)
The 1/9 of an expression is the same thing is the 9th root of the expression.
